[Beignet] [PATCH 2/2] use posix_memalign instead of aligned_alloc to be more compatible

[Guo Yejun]

At some systems, function aligned_alloc is not supported.
>From Linux Programmer's Manual:
The function aligned_alloc() was added to glibc in version 2.16.
The function posix_memalign() is available since glibc 2.1.91.
